SLP's F-Body cat-backs have always been the best-performing exhaust systems in the business. Now they are the most versatile, too! Using our industry-exclusive modular design architecture, we have developed a line of systems that can be quickly reconfigured to fit changing performance, noise-level, and sound-quality requirements. Simply loosen a few band clamps, swap muffler types, retighten, and you are done. No other exhaust offers this level of performance and adaptability!

Along with the included race muffler, the F-Body Loud Mouth system is compatible with our original Loud Mouth II bullet-type race muffler (#31067). Get both for complete control over your car's sound and performance characteristics.

NOTES: Includes Loud Mouth resonator. Loud Mouth II race muffles sold separately.
